Domains: Continuous. Size: 1-D. Kind: Iconic Diagrams (Rotation / Electric).

Description

Potentiometers have a variable resistance according to a certain rotation. By establishing a voltage (see picture below) across the resistor it is possible to get a proportional relation between the angle and the output voltage.

Potentiometer

with

 

Uout = Umax * angle / (turns*2*pi)

 

Here Umax is the maximum voltage and turns is the maximum number of turns.
